Description

자기유도 위치감지 센서{Magnetic inductive type position sensor}Magnetic inductive type position sensor

본 발명은 자기유도를 이용한 위치 센서에 관한 것이다.
The present invention relates to a position sensor using magnetic induction.

로터와 스테이터의 상호 움직임에 따라, 회전축의 위치를 감지하는 센서는 다양한 방식으로 구현 가능하다. 이 중, 자기유도 방식을 이용한 위치 센서의 일 예는 유럽 등록특허 EP1081454와, 미국 등록특허 US6384598에 공개된 바 있다.According to the mutual movement of the rotor and the stator, a sensor for detecting the position of the rotation axis can be implemented in various ways. Among these, an example of a position sensor using a magnetic induction method has been disclosed in European Patent EP1081454 and US Patent US6384598.

상기한 선행기술에서는 로터에 디스크를 마련하되, 상기 디스크에는 부채모양의 방사형상의 날개를 복수 개로 형성하여, 상기 복수 개의 날개와 마주보게 배치된 인쇄회로기판에는, 상기 복수 개의 날개와 대응되는 위치에 전류가 통전되는 회로패턴을 형성하여, 상기 회로패턴에 전류를 통전할 때 발생하는 자기장이 상기 날개와의 상호 작용을 통해 변경되는 값을 이용하여, 상기 로터의 위치를 감지하는 기술이 개시된 바 있다.In the above-described prior art, a disk is provided in the rotor, and the disk has a plurality of fan-shaped radial wings, and the printed circuit board disposed to face the plurality of wings is located at a position corresponding to the plurality of wings. Forming a circuit pattern through which a current is energized, a technique for detecting the position of the rotor using a value that changes when the magnetic field generated when energizing the circuit pattern through interaction with the blade has been disclosed. .

그런데, 이와 같은 종래 기술에 따르면, 디스크에 방사형으로 돌출 형성된 상기 날개들의 평단도가 균일하게 형성되지 못할 경우, 로터 회전 시 상대되는 인쇄회로기판과 날개 사이의 간격이 일정하게 유지되지 못하므로, 자기 유도 특성도 불균일하게 나타날 수 있다. 이러한 기구적인 오차로 인해, 감지센서의 출력특성이 리플(ripple) 현상으로 나타나, 센서 출력특성 오차(error)를 증가시킬 수 있다는 문제점이 있다.
However, according to the related art, when the flatness of the blades radially protruding from the disk is not uniformly formed, the distance between the printed circuit board and the blades that are opposed during the rotation of the rotor is not kept constant. Induction characteristics may also appear nonuniform. Due to this mechanical error, the output characteristic of the sensing sensor appears as a ripple phenomenon, which may increase the sensor output characteristic error.

인쇄회로기판(10)에는 전류가 흐르는 회로패턴(11)이 방사상으로 형성되어 있으며, 소정의 제어부(12)가 실장 될 수 있다. 상기 제어부(12)는 일반적으로 주문형 집적회로(ASCI, application-specific integrated circuit)로 구성될 수 있으며, 동일한 종류의 주문형 집적회로를 한 쌍으로 구성할 수 있다. 또한, 상기 전류를 3상 전원을 인가 받을 수 있다.In the printed circuit board 10, a circuit pattern 11 through which current flows is formed radially, and a predetermined controller 12 may be mounted. The control unit 12 may generally be configured as an application-specific integrated circuit (ASCI), and may be configured as a pair of custom integrated circuits of the same type.

로터(20)는 미도시된 회전축이 중앙에 결합되며, 복수 매의 날개부재(21)가 끝단이 링 형상의 가이드 부재(22)로 연결될 수 있다. 본 발명의 바람직한 일 실시예에 따르면, 상기 로터(20)는 디스크 형상의 몸체에, 프레스 가공으로 동일한 형상의 날개부재(21)를 관통 형성한 후, 끝단은 링 형상을 가지되, 상기 날개부재(21)와 동일한 재질로서 일체가 되도록 구성할 수 있다.The rotor 20 is coupled to the center of the rotation shaft is not shown, a plurality of wing members 21 may be connected to the end of the ring-shaped guide member 22. According to a preferred embodiment of the present invention, the rotor 20 is formed in the disk-shaped body, through the wing member 21 of the same shape by pressing, the end has a ring shape, the wing member It can be comprised so that it may become one with the same material as (21).

다른 실시예로는, 상기 날개부재(21)를 프레스 가공으로 공간부를 절취하여 구성한 후에, 상기 날개부재(21)의 끝단을 링 형상의 고무, 실리콘, 합성수지 재질 중 어느 하나의 재질로 마련된 가이드 부재(22)로 고정하여, 상기 복수 개의 날개부재(21)들을 가이드 하여, 각각의 날개부재(21)들이 상기 인쇄회로기판(10)에 대하여, 일정한 간격으로 이격 될 수 있도록 가이드 할 수 있다.In another embodiment, after the wing member 21 is formed by cutting the space part by press working, the end of the wing member 21 is formed of a guide member made of any one of ring-shaped rubber, silicone, and synthetic materials. By fixing to 22, the plurality of wing members 21 may be guided to guide each of the wing members 21 to be spaced at regular intervals with respect to the printed circuit board 10.

도 2 및 도 3은, 이와 같은 구성을 가지는 자기유도 위치감지 센서의 원리를 이용하여 토크센서를 구성한 상태를 도시한 도면이다.2 and 3 are views illustrating a state in which a torque sensor is configured by using the principle of the magnetic induction position sensor having such a configuration.

도시된 바와 같이, 인쇄회로기판(10)의 내부에는 소정 형상의 회로패턴(11)이 마련되며, 상기 회로패턴(11)과 마주보는 위치로서, 상측과 하측에 제 1 및 제 2 로터(20)(30)가 배치될 수 있다. 한편, 상기 인쇄회로기판(10)의 하측에는 상기 인쇄회로기판(10)을 지지하는 커버부재(15)가 결합되는데, 상기 커버부재(15)는 상기 회로패턴(11)에서 형성되는 자기력을 투자할 수 있는 재질로 마련되는 것이 바람직하며, 수지재질로 형성되는 것이 좋다.As shown in the drawing, a circuit pattern 11 having a predetermined shape is provided inside the printed circuit board 10 and faces the circuit pattern 11. The first and second rotors 20 are disposed above and below. ) 30 may be disposed. On the other hand, the cover member 15 for supporting the printed circuit board 10 is coupled to the lower side of the printed circuit board 10, the cover member 15 invests a magnetic force formed in the circuit pattern 11 It is preferable to be provided with a material that can be, and preferably formed of a resin material.

제 1 로터(20)는 제 1 개수(n1)의 제 1 날개부재(21)가 마련되고, 상기 제 1 날개부재(21)의 끝단에는 별도 부재로 마련된 링 형상의 제 1 가이드 부재(22)가 결합된다. The first rotor 20 is provided with a first wing member 21 of a first number n1, and a ring-shaped first guide member 22 provided as a separate member at the end of the first wing member 21. Is combined.

제 2 로터(30)는 제 2 개수(n2)의 제 2 날개부재(31)가 마련되고, 상기 제 2 날개부재(31)의 끝단에는 별도 부재로 마련된 링 형상의 제 2 가이드 부재(32)가 결합된다. The second rotor 30 is provided with a second wing member 31 of a second number n2, and a ring-shaped second guide member 32 provided as a separate member at the end of the second wing member 31. Is combined.

한편, 상기 제 1 및 제 2 날개부재(21)(31)의 개수는 서로 다르게 구성되는 것이 좋은데, 필요에 따라 제 1 날개부재(21)의 개수를 크게 할 수도 있고, 그 반대로 제 2 날개(31)의 개수를 크게 하는 것도 가능하다.Meanwhile, the number of the first and second wing members 21 and 31 may be different from each other. If necessary, the number of the first wing members 21 may be increased, and vice versa. It is also possible to increase the number of 31).

상기 제 1 및 제 2 날개부재(21)(31)의 개수를 다르게 하는 이유는, 상기 제 1 로터(20)에 연결되는 입력축(미도시)의 비틀림 각과 제 2 로터(30)에 연결되는 출력축(미도시)의 비틀림 각을 각각 측정하여, 상기 제 1 및 제 2 로터(20)(30)에서 측정된 비틀림 각의 평균치를 이용하여, 각도와 토크를 연산할 수 있다.The reason for varying the number of the first and second wing members 21 and 31 is a torsion angle of an input shaft (not shown) connected to the first rotor 20 and an output shaft connected to the second rotor 30. Torsion angles (not shown) may be measured, and angles and torques may be calculated using average values of the torsion angles measured by the first and second rotors 20 and 30.

즉, 상기한 바와 같이 제 1 및 제 2 날개부재(21)(31)의 개수를 다르게 하면, 상기 회로패턴(11)과의 상호작용으로 감지되는 자기변화가 제 1 및 제 2 날개부재(21)(31)의 면적 차이로 인해, 서로 다른 피크의 신호를 감지할 수 있어, 입력축과 출력축의 비틀림 각을 개별적으로 계산할 수 있기 때문이다.That is, when the number of the first and second wing members 21 and 31 is different as described above, the magnetic change sensed by the interaction with the circuit pattern 11 is the first and second wing members 21. Due to the difference in the area of the 31), signals of different peaks can be detected, and the torsion angles of the input shaft and the output shaft can be calculated separately.

한편, 도시하지는 않았으나, 상기 제 1 및 제 2 가이드 부재(22)(32)를 상기 제 1 및 제 2 로터(20)(30)와 한 몸으로 구성할 수도 있다. 즉, 디스크 형상의 상기 제 1 및 제 2 로터(20)(30)에 프레스 가공 등으로, 제 1 및 제 2 날개부재(21)(31)를 형성할 때, 상기 제 1 및 제 2 날개부재(21)(31)들의 끝단이 링 형상으로 연결될 수 있도록, 상기 제 1 및 제 2 날개부재(21)(31)들의 서로 이격된 공간부만을 펀칭 등으로 제거하여 형성할 수도 있다. 이 경우, 별도의 제 1 및 제 2 가이드 부재(22)(32) 조립 공정을 생략할 수 있어 간편하며, 제 1 및 제 2 날개부재(21)(31)를 형성하는 공정 중에, 상기 제 1 및 제 2 날개부재(21)(31)가 휘어지는 것을 방지할 수 있다.Although not shown, the first and second guide members 22 and 32 may be configured as one body with the first and second rotors 20 and 30. That is, when the first and second wing members 21 and 31 are formed in the disk-shaped first and second rotors 20 and 30 by press working or the like, the first and second wing members are formed. The ends of the (21) and (31) may be formed by removing only the spaced portions of the first and second wing members (21) (31) spaced apart from each other by punching or the like. In this case, the assembly process of the first and second guide members 22 and 32 can be omitted, and the first and second wing members 21 and 31 can be omitted. And it is possible to prevent the second wing member (21, 31) is bent.

이처럼, 상기 제 1 및 제 2 가이드 부재(22)(32)를 별도 부재로 마련하여 조립하거나, 상기 제 1 및 제 2 날개부재(21)(31)와 일체화된 구성으로 마련하면, 상기 제 1 및 제 2 날개부재(21)(31)의 끝단이 링 형상의 제 1 및 제 2 가이드 부재(22)(32)에 의해 가이드 되므로, 각각의 제 1 및 제 2 날개부재(21)(31)가 가공공정 중에 높낮이가 서로 다르게 형성되는 것을 방지할 수 있다. As such, when the first and second guide members 22 and 32 are provided as separate members and assembled, or when the first and second guide members 22 and 32 are integrated with the first and second wing members 21 and 31, the first and second guide members 22 and 32 may be integrated. And the ends of the second wing members 21 and 31 are guided by the ring-shaped first and second guide members 22 and 32, so that the first and second wing members 21 and 31 respectively. It is possible to prevent the height is formed differently during the processing process.
